Kuyambitsa zinthu zotenthetsera kwa ng’anjo ya vacuum sintering

Njira yosinthira kutentha kwa ng’anjo yotentha ya vacuum sintering ku workpiece ndi yosiyana ndi ng’anjo wamba yamagetsi yamagetsi, yomwe makamaka imachokera ku kutentha kwa dzuwa. Zinthu zotenthetsera makamaka zikuphatikizapo faifi tambala chromium, kutentha kwambiri molybdenum, graphite ndi graphite lamba (mbale), tungsten lamba ndi tungsten mauna:

(1) Ni-Cr imagwiritsidwa ntchito makamaka m’ng’anjo zomwe kutentha kwake kuli pansi pa 1000 ℃;

(2) High-kutentha molybdenum angagwiritsidwe ntchito pa ng’anjo thupi pansi 1600 ℃;

(3) graphite ndi graphite tepi (mbale) angagwiritsidwe ntchito mu ng’anjo thupi pansi 2300 ℃;

(4) Tungsten lamba ndi tungsten mauna angagwiritsidwe ntchito mu ng’anjo thupi pansi 2400 ℃.

Kusankhidwa kwa chinthu chotenthetsera kumatsimikiziridwa makamaka ndi kutentha kwa sintering, maonekedwe a thupi ndi mankhwala a mankhwala.
